Construct short architecture name from architecture signature.

Map existing architecture signature to short architecture name
at build time. This architecture name is (as yet) unused, but will be used
to build per-architecture cache files with names made unique by including
the architecture name. The auto-detected architecture name can be overridden
with the --with-arch=ARCH configure option.
